Colorectal Neoplasms Clinical Trial
— ADENOMAOfficial title:
Accuracy of Detection Using ENdocuff Optimisation of Mucosal Abnormalities
The purpose of this study is to determine if a new device, called the Endocuff Vision (a small plastic device attached to the end of the colonoscope which helps by holding the folds of the bowel back to give a clear view of the inside of the bowel) will significantly improve the detection of adenomas when used in all patients referred for colonoscopy.

Secondary | Patient satisfaction using validated patient comfort Bowel Cancer Screening Programme (BCSP) questionnaires | Patient satisfaction measured from no pain (0) to severe pain (3), episodes of discomfort from no discomfort (0) to frequent (more than 4 times)(3), length of discomfort from no discomfort (0) to more than 1 minute(3). | 10 months | No |
Secondary | Increase in surveillance colonoscopies caused by increased adenoma detection rate | Increase in surveillance colonoscopies due to increased adenoma detection rate in terms of number of potential follow up procedures based on British Society of Gastroenterology adenoma surveillance guidelines in both groups | 10 months | No |
Secondary | Number of proximal sessile serrated polyps by histology | Number of of proximal sessile serrated polyps in both groups | 10 months | No |

Secondary | Change in adenoma detection rate of each endoscopist during the course of the trial | Adenoma detection rate (ADR) of the first 20% of patients scoped by each colonoscopist with the last 20% of patients in each arm to identify any changes in ADR. | 10 months | No |
Secondary | Adenoma detection rate of individual endoscopist before and after trial commencement | Baseline ADR of each colonoscopist prior to trial recruitment with their individual ADR in patients where Endocuff Vision was not used. | 10 months | No |
